Message App Running on Background

Go to settings/messages. Are you logged in with your Apple ID? If so, you are using it. Tap on Send & Receive, then your Apple ID, and sign out.

I don't use the Message app (I even have it "not allowed" on screen time), and yet, I find it is being used on background (for instance, it seems that it was already used for 1 minute today; 1 minute on screen which my be my checking for activity, and 1 minute on background). I also have the background setting not allowing background use. What is happening?

Are you logged into Facetime? If so, Messages needs to periodically send an authorization message. There may well be other maintenance things it neds to do as well. 2 minutes should not significantly affect your battery.

Maybe iphones allows nearby iphones to use others people' imessages or messages apps to communicate covertly ? Just wondering...

Um, no.

• I found this on google and u think that it would help “You can turn iMessage apps on or off by going to Settings > Messages > iMessage Apps. 
• You can also turn off background app refresh for individual apps by going to Settings > General > Background App Refresh.”

That is partly true (but wrong in details), but irrelevant to the problem reported in this thread.

• There is no such setting as Settings > Messages > iMessage Apps. If you try to go to it you would see that immediately.
• Background App Refresh doesn’t have any effect on event-driven apps such as Messages, because they don’t use background processing.
